BUILT-IN ARCH SUPPORT FOR CALIFORNIA PROCESSED SHOES Filed Feb. 15, 1952 INVENTOR. HENRY ScHEmMAuN United States Patent BUILT-1N ARCH SUPPORT FOR CALIFORNIA PROCESSED SHOES Henry Scheinmann, Kew Gardens Hills, N. Y. Application February 15, 1952, Serial No. 271,703 2 Claims. CI. 36-85) This invention relates to new and useful improvements in built-in arch supports for California processed shoes.

More specifically, the present invention proposes the construction of a California processed shoe to have a built-in arch support as an integral part thereof to support the arch of the foot inserted into the shoe.

Still further, the present invention proposes characterizing the arch support by a resilient pad inserted between the adjacent faces of the inner sole and heel wedge of the shoe and an arch supporting stiffener mounted along the inner face of the upper to extend upward in continuation of the inner side of the resilient pad to combine therewith to form'the arch support for the arch of the foot. Y

- Another object of the present invention proposes forming the resilient pad to be wedge shaped to decrease in thickness from its inner side to its outer side and securing the resilient pad in position between the adjacent faces of the heel wedge and the inner sole so as to have a gradual lifting effect on the. sole of the foot at the arch thereof.

Still another object of the present invention proposes arranging the arch supporting stiffener so that it is adhesively secured to the inner face of the shoe upper and has its bottom edge portion stitched in position in a manner to be fixedly maintained in its position extended upward in continuation of the resilient arch pad.

As a further object, the present invention proposes the inclusion of an auxiliary stiffening means between the adjacent faces of the shoe upper and the arch supporting stiffener arranged and shaped in a manner to cause the arch supporting stiffener to engage the inner side of the arch of the foot with different degrees of stiffness.

It is a further object of the present invention to provide arch supporters in California processed shoes which can be incorporated therein without too much difiiculty, which are effective for their intended purposes and which do not materially increase the cost of manufacture or the ultimate purchase price to the consumer.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

0n the accompanying drawings forming a material part of the present disclosure:

Fig. 5 is an enlarged partial transverse vertical sectional view taken on the line 5-5 of Fig. 4

Fig. 6 is a perspective view of the auxiliary stiffening member used in the form of the invention shown in Figs. 4 and 5.

The California processed shoe, according to the first form of the invention illustrated in Figs. 1 to 3, includes a heel wedge 10 designed to raise the heel end of the shoe, as generally known in the art to which the present invention pertains. Such heel wedges 10 are generally formed of wood for lightness of construction, but may be formed of any desired material. Extended across the top face of the heel wedge 10, there is an inner sole 11 of leather or the like which has its peripheral edge portions 11 turned inward and under, as best shown in Fig. 2.

Extended about the outer periphery of the heel wedge 10 and the fore part of the shoe, there is a platform cover 12 of any decorative leather or resinous plastic material. The platform cover 12 has its top edge portions 12 turned to extend inward across the top face of the heel wedge 10. Similarly, the bottom edge portions 12 of the platform cover 12 are turned inward beneath the heel wedge 10 and secured in position by a thin layer of waterproof cement 14.

A wear or outer sole 15 is extended across the full bottom of the shoe including the bottom face of the heel wedge 10. The outer sole 15 is secured in position on the bottom of the shoe by a thin layer of waterproof cement 16. The outer sole 15 is made of leather, rubber or one of the synthetic sole materials.

The shoe further includes a shoe upper 17 of any desired construction and which can be made of leather, cloth or a synthetic resinous material. On the drawing, the shoe upper 17 is illustrated as being of the open toe and the open heel type with its bottom edge portions 17 inserted between the adjacent faces of the inturned edge portions 11 of the inner sole 11 and the inturned top edge portions 12* of the platform cover 12.

The meeting edge portions 11 12 and 17* are fixedly joined together by a single line of stitches 18, see Fig. 2, parallel to the outer periphery of the shoe sole, all als1 known in the art of constructing California processed s oes.

Up to this point the construction of the shoe is known to those versed in the shoe art. The built-in arch support of the present invention is comprised of a resilient arch pad 19 and an arch supporting stiffener 20. The resilient arch pad 19 is made of sponge or foam rubber and is substantially semi-circular in plan. The straight side 19 of the resilient arch pad 19 is made slightly reentrant to conform to the shape of the inner side of the heel wedge 10 at the arch portion thereof. In addition, the resilient arch pad 19 is made slightly thicker at its inner side 19 and of diminishing thickness in section in all directions from that side 19 As best shown in Fig. 2, the resilient arch pad 19 is inserted between the adjacent faces of the heel wedge 10 and the inner sole 11 and is fixedly retained in position by layers of cement 21. Where the inner sole 11 extends beyond the outer periphery of the arch pad 19, one of the layers of cement 21 serves to securely anchor the inner sole 11 in position. The resilient arch pad 19 is positioned with its reentrantly curved inner side 19 extended parallel with the inner side of the heel wedge 10, see Fig. 2, at the arch thereof. Thus, the arch pad 19 by reason of its diminishing thickness toward its outer periphery, has a gradual and comfortable lifting effect on the arch of the foot.

The arch support stiffener 20 is preferably made of a relatively stiff piece of leather cut to the shape shown in Fig. 1. However, the arch support stiffener 20 may if desired be made of a piece of synthetic resinous material. The arch supporting stiffener 20 is extended along the inner face of the shoe upper 17 in upward continuation of the resilient arch pad 19. A layer of cement 22 between the adjacent faces of the shoe upper 17 and the arch supporting stiffener 20 mounts the stiffener fixedly in position on the inner face of the upper 17. In addition, the arch supporting stiffener 20 has its bottom edge portion 20 inserted between the inturned edge portion 11*- of the inner sole 11 and the inturned bottom edge portion 17 of the shoe upper 17, so that the same line of stitches 18 which joins the meeting edge portions 11 12 and 17 will also serve to anchor the bottom edge portion 20 of the arch supporting stiffener 20, see Fig. 2.

The relationship between the resilient arch pad 19 and the arch supporting stiffener 20 is such that the arch supporting stiffener functions to continue the comfortable uplift of the arch pad 19 the'footand-at thea-rchthereof. Thus, it*w1llbeapp reciated that the arch pad 9 and the arch supporting stifiener combine to provide the California processed shomwifln amarchsupport which;will functiomto: support thezarclr of; the; font: inserted; into thez shoe;
